Using Scala with Sling Page edited by Alex Parvulescu Changes (4) ... There are two example applications available in {{/contrib/scripting/scala/samples}}: A simple Hello World programm and a more advanced Forum application. The examples require the Apache Sling Sample Path Based Resource Type Provider bundle. So lets install this bundle first: * Goto {{/samples/path-based-rtp}} and type {{mvn org.apache.sling:maven-sling-plugin:install}}. * Goto {{/samples/path-based-rtp}} and type {{mvn -P autoInstallBundle clean install -Dsling.url="" Now the examples themselves: * Install the Scala for Sling Demo Application - Hello World bundle. Goto {{/contrib/scripting/scala/samples/hello-world}} and type {{mvn org.apache.sling:maven-sling-plugin:install}}. -P autoInstallBundle clean install -Dsling.url=""> The hello world application is then available at [http://localhost:8080/content/helloworld.html] [http://localhost:8888/content/helloworld.html] * Install the Scala for Sling Demo Application - Forum bundle.

Full Content Using Scala with Sling Sling supports the Scala programming language version 2.8.1 through optional modules located in /contrib/scripting/scala. Installation The following bundles are required for Scala support: scala-library, scala-compiler, Scala Script Engine, Apache Sling Scala Scripting Configuration. Note: In order to see the Scala scripting engine in action you can also use the Launchpad Contrib Testing module which comes with all necessary bundles (including the examples) pre-installed. See below. Manual installation Start Sling Download the scala-library bundle and the scala-compiler bundle and install them using for example the Apache Felix Web Management Console. Install the Scala Script Engine bundle. Goto /contrib/scripting/scala/script and type mvn org.apache.sling:maven-sling-plugin:install. Install the Apache Sling Scala Scripting Configuration bundle. Goto /contrib/scripting/scala/config and type mvn org.apache.sling:maven-sling-plugin:install. Using Launchpad Contrib Testing Goto /contrib/launchpad/testing and type mvn jetty:run -Pjcrinstall-tests to start Sling. Sling is now running at http://localhost:8888/. All required bundles and examples are pre-installed. See next section on how to access the examples. Remember to substitute the port number with 8888! See /contrib/launchpad/testing/README.txt for details. Examples Applications There are two example applications available in /contrib/scripting/scala/samples: A simple Hello World programm and a more advanced Forum application.

The hello world application is then available at http://localhost:8888/content/helloworld.html Install the Scala for Sling Demo Application - Forum bundle.

The form application is the available at http://localhost:8888/content/forum.html?sling:authRequestLogin=true. When prompted for credentials use admin/admin. Configuration The Scala scripting bundle is configurable through the Apache Felix Web Management Console (PID: org.apache.sling.scripting.scala.config.SlingSettingsProvider). Scala compiler options. Scala compiler settings as documented by scalac -help. Default is blank. Compiler output directory. Output directory for files generated by the Scala compiler. Default is /var/classes.
